TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to a premium class aircraft passengersuite that includes several unique features that provide enhancedpassenger comfort, weight savings and efficient space utilization. Thepassenger suite includes a separate seat and bed that permit the seatand bed structures to be optimized for sitting and sleeping,respectively. Other features permit the passenger suite to beefficiently used by the passenger for sleeping, working, dining andvideo viewing.

Conventional prior art aircraft passenger suite beds are typicallyformed by reclining an aircraft seat back into generally horizontalalignment with a seat bottom, and then providing additional sleepingroom by using a leg and/or foot rest or ottoman as supplementalsurfaces. This arrangement has the disadvantages of providing a sleepingsurface that is too hard for comfortable sleeping, having gaps or spacesbetween the bed segments that are uncomfortable, and requiring that thebed be “made up” by a flight attendant after bed deployment duringflight while the passenger waits in the aisle.

The present invention offers a solution to these problems by providing abed that is a separate and distinct structure from the passenger seatand that deploys into a flat sleeping surface having a proper firmness,and that is already covered with a sheet or other bed covering, whichcan therefore be prepared for use during aircraft servicing inpreparation for flight. Other features include the ability of thepassenger to move to a more comfortable, ergonomic upright chair forworking and/or dining, and the ability of a second passenger to work ordine with the suite occupant—one passenger occupying the main seat, andthe second passenger occupying the work/dining chair.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings, a premium class passenger suite 10 isshown, and includes front and rear privacy panels 12, 14 and a slidableside privacy panel 16. The suite 10 in FIGS. 1 and 2 views extends alonga length of the aircraft fuselage “F”, which forms one side of the suite10.

A main seat 20 that includes a seat back 22, seat bottom 24, and leftand right armrests 26, 28 is provided for passenger use during taxi,take-off, landing and in-flight relaxation, video viewing, upright orsemi-reclined reading and the like. A work/dining chair 30 sits on astorage box 32 at right angles to the main seat 20. The suite 10 alsocontains work/dining tables 34, 36, a video display monitor, main seatcontrols and electronics controls, not shown.

As shown in FIG. 2, an elongate cabinet 40 extends along the length ofthe suite 10 adjacent the aircraft fuselage “F” and contains a roll-outmembrane bed 42.

The main seat 20 and bed 42 are separate elements. The seat back 22folds forward, stowing face down above the seat bottom 24, and at thesame time the left and right armrests 26, 28 are lowered, making spacefor the roll-out membrane bed 42. As is best shown by comparing FIG. 1and FIG. 2, the bed 42 occupies the space above the folded seat back 22and the space that was previously occupied by the seat back 22 in itsupright position when in use as the seat. As is also shown, the foot endof the bed 42 is supported over the dining chair 30. The movement of theseat bottom 24, seat back 22 and deploying bed 42 are electronicallydriven, interlinked and operated by a single switch.

When the bed 42 is deployed, a 2 inch gap is provided between the stowedsurface of the seat back 22 and the underside of the bed 42. This 2 inchgap allows for a deflection of the bed 42 to create comfort for therecumbent passenger.

The bed 42 is formed in one complete flexible surface that includes anunderlying membrane 44 that supports a mattress 46, without joints inthe mattress 46, as opposed to combination multiple padded surfaces,such as is common in lay-flat aircraft seating. A suitable material foruse as the membrane 44 is a synthetic polymer sold under the trademarkKrystalFlex. By designing the main seat 20 and the bed 42 as separateelements that do not need to convert from one use to another, each canbe designed to optimize the comfort for its intended use. The bed 42stows in a compact space within the cabinet 40 that is approximately 8.7inches wide. The bed 42 deploys with the sheet or other bed coveringsattached to it ready for the passenger to use.

As is shown in FIG. 3, the bed 42 is folded to fit into the cabinet 40when stowed. As shown in FIGS. 4 and 5, the membrane 44 rolls out of thecabinet 40 transversely across the width of the suite 10 into its lieflat configuration, and as shown in FIG. 2, provides a 30″ wide bed 42which stows into the 8.7 inch space referenced above. FIG. 5 illustratesthis movement with the membrane 42, but the overlying mattress 46 is notshown.

As is shown in FIGS. 6-8, the bed 42 includes drive belts 50 and 52 thatdeploy the bed 42 from its folded and stowed position. The bed 42 isconstructed of a support beam 54 with the flexible membrane 44 andmattress 46 suspended from the support beam 54 and the two drive belts50 and 52. See FIGS. 8 and 11. The static end of the bed 42 is attachedto the cabinet 40. The drive belts 50, 52 move the support beam 54 andthe attached membrane 42 from the cabinet 40 and into its horizontaldeployed position.

The bed 42 includes a tensioning apparatus 60 that guides the bed 42smoothly between its stowed and deployed state. As is shown in FIGS. 7,9 and 10, the tension is provided by a pneumatic cylinder 62 that exertsresistance pressure against the direction of movement of the drive belts50, 52. The cylinder 62 also provides tension sufficient to providesupport to the bed 42 under the weight of the recumbent passenger.

The tension cylinder 62 is connected to a control arm 64 mounted forpivotal movement. A series of guide rollers 66, 68, 70 and 72 carries atension membrane 74 that is attached at a distal end to the support beam54. The tension membrane 74 is stored on the roller 66 when the bed 42is stowed.

To deploy the bed 42, an actuator motor assembly 80 drives the drivebelts 50, 52 clockwise. The drive belts 50, 52 pull the support beam 54to which is attached the bed membrane 44, which is carried by the drivebelts 50, 52 across the width of the suite 10. At the same time, thetension membrane 74 deploys while under tension by the pneumaticcylinder 62.

Referring now to FIG. 12, an overall view of the seat 20 indicates thatthe seat back 22 is moveable in a forward translated manner onto theseat bottom 24 for stowage in a horizontal position immediately abovethe seat bottom 24. The seat back 22 is linked to the kinetic path ofthe seat bottom 24, and the seat back 22 is driven by a single motor.The seat 20 is mounted on a seat base 50 attached to the aircraft deckwith suitable track fittings.

Referring now to FIGS. 13 and 14, the seat base 50 includes left andright side panels (only left side panel 52 shown) that includes a track54 on which is mounted a link 56 with rollers 58, 60 carried on apivotally-mounted arm 62. The rollers 58, 60 are mounted for movement inthe track 54, as shown. A linear element 64 is positioned on the baseand mounts a slide element 66. By comparing the positions of the rollers58, 60 and the slide element 66 in FIGS. 14, 16 and 18, the movement ofthe seat back 22 into its stowed position is clearly illustrated. Notethat the link 56 drives the seat back 22 into its stowed position at theend of the kinematic path defined by the track 54. Though not shown, theelements described above are found on both right and left sides of theseat 20 and operate to balance the forces operating on the seat back 22and spread them across the width of the seat 20.

The stowage of the seat back 22 is accomplished by the movement out ofthe seat back 22 automatically as part of the seat's kinetic path. Theseat back 22 folds forwardly out the way of the separate deployed bed42, and does not form part of the bed 42. For these reasons, the bed 42and the seat 20 can be each designed with materials that lead tosignificantly higher degrees of comfort for both, rather than withmaterials that serve both as a seat and bed and compromise the comfortof both.

Referring now to FIGS. 19 and 20, the relative positions of the stowedand deployed work/dining chair and the deployed and stowed bed 42 areillustrated in FIGS. 7 and 8.

FIGS. 21, 22 and 23 show the work/dining chair 30 in its stowed,intermediate and deployed positions. Chair 30 includes an L-shapedsupport structure 54. The support structure 54 supports the upright seatback 50 and seat bottom 52. The deployed seat bottom 52 occupies spacethat the deployed bed 42, see FIG. 20, must also occupy. For thisreason, the seat bottom 52 must be stowed before the bed 42 is deployed.In order to avoid requiring the flight attendant or passenger attend tothis function and possibly forget to stow the seat bottom 52, thisfunction is carried out automatically. As is shown in FIGS. 21 and 22,an electromagnet 56 is positioned on the support 54 adjacent the rear ofthe seat bottom 52. A block of ferrous material 56 is positioned on therear part of the lower surface of the seat bottom 52 proximate theelectromagnet 56. The seat bottom 52 is normally held down in ahorizontal, deployed position by the energized electromagnet 56. Theelectromagnet 56 is electronically synchronized with the bed 42deployment mechanism, and as the bed 42 begins to deploy theelectromagnet 56 is de-energized, releasing the seat bottom 52 andallowing it to rise to its stowed position under the influence of aspring, pneumatic actuator or other lifting mechanism. FIGS. 24 and 25further illustrate the spatial relationship between the work/diningchair 30 and the bed 42.

Referring now to FIGS. 26 and 27, the function and operation of thetable 34 is shown. Reference back to FIG. 1 shows the table 36 in itsstowed position. In their stowed positions the tables 34, 36 rest on thetop surface of the cabinet 40. The table 34 is positioned in a foldedposition in a slide bracket 44. The table 34 is formed of two tablepanels 34A, 34B attached by a piano-type hinge that permits the tablepanel 34B to be opened into the position shown in FIG. 26. The table 34is further deployed by pulling the table out and away from the cabinet40 by means of the slide bracket 44 and, as well, shifting the tablelaterally if desired. Table 34 is ideally suited for use as a work anddining table. The work/dining chair 30 provides the passenger with acomfortable chair with an upright back. The cabinet 40 includes a frontpanel 46 behind which is stowed the bed 42 when not in use. The frontpanel 46 includes a recess 48 which permits the feet of the occupant ofthe chair 30 to be positioned in a natural, comfortable position.

FIG. 27 shows the table 34 deployed from its position on the cabinet 40.

In one arrangement, the passenger seated in the chair 30 can also usethe table 36 as a further work or meal surface while also using thetable 34. Table 36 is mounted on the cabinet 40 on a pivot arm, notshown.

In another arrangement, a second passenger may sit in the main seat 20and, by rotating the table 36 into position in front of the main seat20, use the table 36 as a meal or work table. Thus, two passengers mayuse the suite 10 at the same time to dine or work together. Thisarrangement thus provides comfortable, spacious accommodations notpresently found in any aircraft environment.
